i recently got in an accident, about 2 months ago, and i smashed up the front of my car on a telephone pole. when i got it back and everything was fixed (or so i thought) i continued driving it daily as i once had. lately during the heat of the summer, however, i have noticed that the a/c does not work. no matter how long the car runs, the a/c never gets cold, it just blows air which is the same temp. as the outside air. i brought it back to the shop where i had it repaired and they checked the freon levels and said it was normal and they didnt know what could be wrong. anyone have any ideas what could be wrong? thanks for any advice
